Asynchronous Receiver/Transmitter (UART) interface supporting multiple devices on a single bus Low-Drift Internal Voltage Reference, 10 ppm/В°C
typical 28-lead 5x5 QFN package Extended Temperature Range -40В°C to +125В°C The MCP39F501 is a highly integrated, single-phase
power-monitoring
IC
designed
for
real-time
measurement of input power for AC/DC power
supplies, power distribution units and industrial
applications. It includes dual-channel delta sigma
ADCs, a 16-bit calculation engine, EEPROM and a
flexible 2-wire interface. An integrated low-drift voltage
reference with 10 ppm/В°C in addition to 94.5 dB of
SINAD performance on each measurement channel …
